• How do I setup a proper VPN for my friends to play LAN games AND give them internet access?

  - by Gizmo

  I'm trying to setup a VPN on my local network, but everyone who connects to me DOES have access to my laptop but not to the internet or other devices on the network. How can I properly configure my VPN on windows to work correctly (giving internet + access to all devices on my network to the remote pc)? Or is there software on windows which makes creating a VPN server easier? or maybe a VMWare image linux vpn server? I can't find any of those! My requirement is that my friends don't have to install additional software, they have to be able to connect with default windows stuff. My OS is Windows 8 Standart edition (not pro or enterprise) OEM. Most of my friends have also windows 8, some windows 7. Extra info: My device is DMZ'ed (Demilitarized Zone, [disabled NAT on my device so it's accessible on the WAN]) I can access files, websites and services on other devices on my network, and all devices can access file shares, website and all other services on my device When enabling VPN everything works except the client is unable to get internet access or access to any device on my network, client has only access to my device.

• Remote offscreen rendering

  - by redmoskito

  My research lab recently added a server that has a beefy NVIDIA graphics card, which we would like to use to do scientific computations. Since it isn't a workstation, we'll have to run our jobs remotely, over an ssh connection. Most of our applications require doing opengl rendering to an offscreen buffer, then doing image analysis on the result in CUDA. My initial investigation suggests that X11 forwarding is a bad idea, because opengl rendering will occur on the client machine (or rather the X11 server--what a confusing naming convention!) and will suffer network bottlenecks when sending our massive textures. We will never need to display the output, so it seems like X11 forwarding shouldn't be necessary, but Opengl needs the $DISPLAY to be set to something valid or our applications won't run. I'm sure render farms exist that do this, but how is it accomplished? I think this is probably a simple X11 configuration issue, but I'm too unfamiliar with it to know where to start. We're running Ubuntu server 10.04, with no gdm, gnome, etc installed. However, xserver-xorg package is installed.

• Only receiving one document at a time from new web server.

  - by Robert Kuykendall

  We're trying to move our internal ticketing system from a Microsoft Small Business Server in the server closet to a Rackspace Cloud Server. The install is Fedora 11 LAMP, and should be default out of the box, except for the vhosts appended to the bottom of the httpd.conf. The new server is suffering from crippling load times, and watching the page load in Firebug it's easy to see the problem occurring, but I can't figure out the cause. Here is the [old server] (http://rkuykendall.com/uploads/old.server.png). I was expecting something like this, but a little slower since it was no longer hosted locally. Instead, the [new server] (http://rkuykendall.com/uploads/new.server.png) appears to only serve one file at a time. Here's another example of this [staircase load time effect] (http://rkuykendall.com/uploads/staircase.png) and another very clear example of the [staircase effect] (http://rkuykendall.com/uploads/staircase2.png). I talked to some guys on Freenode #httpd with no luck. I created a duplicate server to play with, and also created a fresh server with Fedora Core 13 and moved over just the database and web files with no luck. Any suggestions?

• DVD/CD burning .zip: is it more reliable, faster, longer lasting to burn a zip of files rather than the files as a folder?

  - by Rob

  Is it more reliable, faster, longer lasting to burn to CD/DVD a zip (or a few large zips) of files rather than the files as a folder? Just thinking if 1000s of small files would not be as efficiently recorded compared with one or a few large zips. Also, even after the burning program verifies the disc, I also use Beyond Compare to compare the files with those on the disc. Always binary compares as identical but I hear the drive stuttering presumably as the head is being shifted only slightly each time to seek the next file, which leads me to think that its best to make one or more zips and copy those locally to compare. Or is it that burning invidual files to the disc is not as readable which causes the head to stutter. There aren't any problems, my disc burns are reliable, just thinking more of efficiency and longevity, the discs burn and verify fast enough on my 18x DVD burner. I'm using ImgBurn mostly. Also used Nero in the past. I burn whole discs closed, finalised. Not sure which write mode but would think Disc At Once from a temporary cached image made by the burning program would be the most reliable.

• Why is REMOTE_ADDR only sometimes available as an Apache environment variable?

  - by Xiong Chiamiov

  To avoid having to parse X-Forwarded-For in Varnish, I'm trying to just set a header on the SSL terminator (currently Apache) that stores the direct client IP in a header. On our development machine, this works: RequestHeader set X-Foo %{REMOTE_ADDR}e However, in staging it doesn't. Specifically, the header is empty, as illustrated by both varnishlog: 13 TxHeader b X-Foo: (null) (On the development machine, this shows the IP address as expected.) Similarly, logging REMOTE_ADDR shows that it only appears to be populated on the dev machine: # Config LogFormat "%{X-Forwarded-For}i %{REMOTE_ADDR}e" combined CustomLog "/var/log/httpd/access_log" combined # Log file, staging <my ip> - # Log file, development <my ip> <my ip> Since the dev machine is, well, a dev machine, it is different in a number of ways; however, I can't track down which difference is causing this. The versions of Apache are the same (2.2.22), and I don't see anything relevant in any of the standard config files or /etc/sysconfig/httpd. And the rest of the system is reasonably similar, since they're built off the same CentOS 5 base image. I can't even tell from the Apache documentation whether REMOTE_ADDR is expected to exist or not as an environment variable, but it clearly works on one machine, whether by fluke or design, and the inconsistency is driving me mad.

• How should I configure backup of my server?

  - by ed209

  I have just rented a dedicated server. If it helps this is the config I have: CPU1 Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (Cores 8) RAM 15975 MB Disk /dev/sda doesn't contain a valid partition table (=> /dev/sda doesn't) Disk /dev/sdc doesn't contain a valid partition table (=> /dev/sdc doesn't) Disk /dev/sdb doesn't contain a valid partition table (=> /dev/sdb doesn't) Disk /dev/sda: 120.0 GB (=> 114 GIB) Disk /dev/sdc: 3000.6 GB (=> 2861 GIB) Disk /dev/sdb: 3000.6 GB (=> 2861 GIB) /dev/sda is a 120GB SSD. This is where I have Ubuntu/lamp installed. It's the drive that will run my site. With the account I got two other drives of 3000GB each which I really don't need but they came with the account. I figured I could use these to back up my main 120gb drive. So a couple of things I wondered were: Should I use these for backups? How should I back up. The data I want to back up is a user uploads directory full of images and the database. Everything else is either in a code repo or backed up some other way. For example, it would be nice to know there is a disk image of the 120gb drive somewhere that I can copy over should there be any problems but equally I don't mind doing a fresh install of all the software and copying over just the images and database dump. Thanks for your advice! (also, happy to not use the two other drives and backup elsewhere if it's more sensible)

• Apache intermittently aborting requests

  - by Adam Phillips

  I have just been dealing with a problem whereby http requests are being aborted, seemingly at random. On any particular page in the website, when you opened a page, a number of the assets (img, css, etc) failed to load. If you refreshed, the page may work fine, the same set of assets may fail to load or different assets may fail to load. The net tab in firefox was returning 'Aborted' in the HTTP status code column for the failed assets, even tho in the case of images, the image previews were still working. There was nothing in any of the apache logs about the requests that failed, however since it seemed to point to an apache issue, we restarted apache. The first time we tried, it made no difference but about 10 minutes later, in the absence of a better solution we tried again. Bizarrely, the problem disappeared immeadiately. So now the site seems to be running fine again but its rather unsettling, both the intermittent nature of the problem and the lack of an explanation for its resolution. Has anyone seen anything like this before and if so did you find out the reason behind it? Many Thanks

• Utilu IE Collection IE6 crashes under Windows 7

  - by Aron

  I've installed Utilu IE Collection under Windows 7 64-bit, but am unable to successfully run IE6 (specifically, "Internet Explorer 6.0 (6.00.2900.2180)"). I haven't tried other versions of IE from the package, so their behavior is unknown. It starts up fine, but the address bar isn't shown. (Attempted to post image, but I'm a newbie on SU and it wouldn't let me. Can be found here.) View-Toolbars shows 'Address Bar' already selected. If I try to (de-)select Address Bar in that list, it crashes: Problem signature: Problem Event Name: APPCRASH Application Name: iexplore.exe Application Version: 6.0.2900.2180 Application Timestamp: 41107b81 Fault Module Name: StackHash_e162 Fault Module Version: 0.0.0.0 Fault Module Timestamp: 00000000 Exception Code: c0000005 Exception Offset: 00000000 OS Version: 6.1.7600.2.0.0.256.48 Locale ID: 1033 Additional Information 1: e162 Additional Information 2: e1625455580a00d3fda64a8cdf366fbb Additional Information 3: 58c7 Additional Information 4: 58c75753c6745fad91929ab6430a83fa That's not all that's wrong ('Search' pane has no contents as well, probably more), but it's the most glaring problem. I've seen some allusions to a registry change needed to fix this, but haven't been able to find any details. Anybody? I'm running the latest version of the collection, 1.7.0.6.

• Best solution top keep data secure

  - by mrwooster

  What is the simplest and most elegant way of storing a small amount of data in a reasonably secure way? I am not looking for ridiculous levels of advanced encryption (AES-256 is more than enough) and I am only looking to encrypt a small number of files. The files I wish to encrypt are mostly comprised of password lists and SSH keys for servers. Unfortunately it is impossible to keep track of ever changing passwords for my servers (and SSH keys) and so need to keep a list of the passwords. Obviously this list needs to be secure, and also portable (I work from multiple locations). At the moment, I use a 10MB encrypted disk image on my mac (std .dmg AES-256) and just mount it whenever I need access to the data. To my knowledge this is very secure and I am very happy using it. However, the data is not very portable. I would like to be able to access my data from other machines (especially ones running linux), and I am aware that there are quite a few issues trying to mount an encrypted .dmg on linux. An alternative I have considered is to create a tar archive containing the files and use gpg --symmetric to encrypt it, but this is not a very elegant solution as it requires gpg to be installed on every system. So, what over solutions exist, and which ones would you consider to be the most elegant? Ty

• Can I select which folders the Photos live tile chooses from?

  - by nhinkle

  The built-in Photos app in Windows 8 has a live tile on the start screen that shows photos from your pictures library. It's a cool little visual, even if it's not particularly useful. The problem is that a lot of image files on my computer are not really photos per se -- I have a lot of screenshots, PNGs of technical drawings, graph images, etc. Those all look pretty awkward on the start screen. I look pretty awkward on the start screen too... sometimes photos like resume profile shots show up that I don't want to delete, but they're not really what I want to be staring at when I start my computer up. I'm looking for some way to configure which folders the Photos app should look in for images to display on the live tile. That way, I could point it to some directories of pretty scenic pictures I've taken, and not have to see graphs and my own mug. For the time being, I've just disabled the live tile (right click - disable live tile), but I would ultimately like to have this functionality, just with more control over it.

• Ping results "echo'd" out to a text file on Windows XP machine has unusual character rather than the outcome

  - by Richard Rice

  Here is the situation. I have a Windows XP machine that I would like to ping another machine and send the output to a text file for review at a later date. This is quite a standard question with several answers on this website and others. The issue I have is that when reviewing the txt file afterwards, the outcome of the ping appears as a strange character. A screenshot of the text file output can be found at the following link. Please note its the first 8 ping outputs that have a strange character. The %%B was me hoping that would output what I wanted! (Cannot upload image to any hosting websites because the company I work for seems to be afraid of them ....) Here is the code I'm using: @echo off For /f "tokens=1-2 delims=/:" %%b in ("%TIME%") do (set mytime=%%a%%b) PING 1.1.1.1 -n 1 -w 1000 >NUL for /f "tokens=*" %%A in ('ping 192.168.5.2 -w 10 -n 1') do (echo %date% %time% %%A >> C:\Temp\Ping_Checks\GarrickSide.txt && GOTO Ping ) :Ping PING 1.1.1.1 -n 1 -w 1000 >NUL for /f "tokens=* skip=2" %%A in ('ping 192.168.5.2 -w 10 -n 1') do (echo %date% %time% %%A >> C:\Temp\Ping_Checks\GarrickSide.txt && GOTO Ping ) This code works fine on a Windows 7 machine, but not on a Windows XP machine. It appears that the echo command isn't outputting the right data, but I don't understand this enough to correct it. Can anyone spot where I'm going wrong?

• Why am I getting programs stuck in log_wait_commit under Linux?

  - by staticsan

  There is something subtly wrong with my Linux install that I just can't locate. It is Ubuntu Lucid Lynx (10.04) 64-bit. Hardware is a Dell Optiplex 960: Intel Core 2 Quad CPU, 8Gb of RAM, 2x 300Gb HDDs. /home is ext2 on one disk and everything else is on the other (/ is also ext3). I have VirtualBox running a 64-bit Vista image for Outlook calendaring, but the heavyweight apps are IntelliJ, NetBeans, MySQL and Opera. Opera also loads my mail (IMAP) of which there is over 10,000 messages. The problem is that Opera stalls for a few seconds from time-to-time. Watching the process list shows it's in log_wait_commit which means (as far as I have figured out) the filesystem is holding things up. Sometimes I can make this happen by doing a subversion update, but usually it happens for no reason I can see. It usually happens to Opera, but I've seen NetBeans go under, too. It doesn't make the app crash - it's just completely unresponsive for a few seconds. Googling has not helped. The closest I got was to remove the sync attribute in the file system. This achieved nothing. On the advice of a Linux guru friend, I lowered /proc/sys/vm/dirty_writeback_centisecs to 300, but that didn't do anything, either. And it was all he could think of. What is going on and can I fix it? (And how?)

• Change the background color of selected text in Google Docs to increase readability [migrated]

  - by gene_wood

  How can I override or change the background color of text selected in Google Docs? It is difficult for me to see the difference and I would like to increase the contrast or difference. After Google restyled Google Docs last year (or earlier this year), I've been unable to see selected text. It's possible this is a visual deficiency with my eyes. In Google Docs, under both Google Chrome (17.0.963.83 (Official Build 127885) m) and Firefox (11.0), when I select text inside a Google Doc, the selected text has a background of color #d6e0f5. Compare this to the default browser background color of #2f65c0. (I determined the color of the selected text background by taking a screenshot and using the color picker tool in Photoshop). I've tested this using a brand new Firefox profile as well as google chrome profile. Here's a section of a screenshot showing the selected text : I've tried using a userscript to override the CSS to go back to the default text selection color using the "Stylish" plugin with this css : ::selection { background:#2f65c0; color:#ffffff; } ::-moz-selection { background:#2f65c0; color:#ffffff; } ::-webkit-selection { background:#2f65c0; color:#ffffff; } This code works on other sites, but I'm unable to get it to work on Google Docs. (I tested on other sites but applying the userscript to a different domain and using bright yellow instead of the default dark blue #2f65c0.) When you use Google Docs, do you have the same color background for selected text or something different? (To test this, browse to docs.google.com , create a document, type text into the document, select the text with the mouse by dragging over it, take a screenshot, load the screenshot up in an image editor and determine the background color of the selected text.) This color differential (between light blue #d6e0f5 and white #fffff) may be easy to see for others and the problem lies with my eyes.

• Booting Windows from different partition than system

  - by szamil

  I have bought an SSD disk, but my laptop (Dell Precision M6300) refuse to use it as a target disk for windows (AHCPI on/off, BIOS up-to-date). I can't exchange the disk unfortunately... But fortunately, I've managed to install windows using USB disk case. The problem is, that when I put that disk as my internal drive it can't boot. (Disk read error, Three Finger Salute ... ) So I tried with Linux (openSUSE), I manage to install it as well, but when I tried to boot GRUB from internal drive I get errors again. (Should I try GRUB2?) I figured out that I can boot into that internal hard drive's openSUSE system using small USB drive with GRUB, kernel and image on it. So, I just run GRUB from USB drive, it loads necessary stuff from the USB drive and then continues from the internal drive. I want to do the same with Windows. But GRUB (rootnoverify and chainloader +1) does not boot my windows on internal drive. The question: is there any chance to copy the critical windows' boot files into the USB drive, to make it possible to boot from that USB drive, but continue booting from internal (different in general) drive? The USB drive would became a system hardware key! ;-) Disk: Plextor M5S 128GB Sata III, laptop has Sata II, but it's compatible anyway, right?

• Should I update the kernel on a Linux machine?

  - by Legate

  As I understand it, updating to a new kernel (with the normal linux-image... package, not by rolling my own) requires a server restart. However, one of our servers (Ubuntu 10.04) is running several extensive screen sessions. Restarting kills those which is always a major hassle to their owners (mostly because of lost session histories). What should I do? I see several possibilites: Not doing anything, that is update only non-kernel packages (perhaps use apt-pinning?) Update the kernel, but not restart. (Is that smart? I seem to remember there might be some problems with loading kernel modules.) Updating the kernel and restarting. Is there perhaps some way to preserve the screen sessions? I guess it ultimately boils down to this question: How important is it to update the kernel? I posted this question here instead of askubuntu.com as I think this is not an Ubuntu-specific issue though this server is running Ubuntu.

• Unable to create files in a directory

  - by vamsi360

  I have created a directory in Virutalbox. Using VBoxManage, I am executing a script inside the Ubuntu VM directory I created above from Ubuntu host OS. But if the script in the VM contains commands for creating a new file, they are not executing. "echo" commands before and after the touch ommand are working fine. I even used root user for VBoxManage to install. I think the directory is not allowing the files to be created . How can I make a directory in Linux to be 777 to all new files created automatically. I mean, even if I make the directory (chmod 777 dir), I am unable to execute the script from the host. Please help. It may be simple permissions problem. Even root is unable to execute. VBoxManage guestcontrol "Ubuntu_10_04" execute --image "/bin/bash" "/home/cloudlet/Desktop/temp2/three" --username root --password root --verbose --wait-exit --wait-stdout -- -l /usr Please help. I am struggling with this problem for the past one week.

• How to copy a floppy boot disk?

  - by Sammy

  I have a floppy boot disk and I would like to copy it to preserve it, as a backup. If I have two floppy drives, A and B, how can I copy the disk? Assuming one has two floppy drives Can I simply insert the floppy disk in one of the drives and then an empty floppy disk in the other and issue a simple command like this one. A:\>copy . b: Will this only copy the contents of the current directory and none of the files in subdirectories? Do I have to explicitly specify the option to copy everything? Also, what about the boot information? That won't get copied, right? If one has only one floppy drive... How do you copy a floppy disk if you only have one floppy drive? Do you in fact have to copy its contents to the local hard drive C and then copy that to an empty floppy disk using the same floppy drive? A:\>copy . c:\floppydisk A:\> A:\>c: C:\> C:\>copy floppydisk a: C:\> I'm guessing I will need some type of disk image tool to really copy everything on a bootable floppy disk. Something like the dd command on Linux perhaps? Am I right?

• Find out what fonts are being sent to a printer

  - by user38307

  I have an issue where two computers running XP and with identical print drivers have different behavior printing over parallel port to receipt printers. For one type of receipt, receipt printing is instant. For another kind printing is delayed by ten seconds on most machines but not on the other. This happens even if I swap out printers. I believe the delay is because this computer has a different set of fonts installed. (It is used for graphic design.) The printers have built-in fonts, and if you do not use one of the built-in fonts the printer has to build up an image in memory rather than just spitting out its fonts. For a particular kind of receipt with special fonts on a particular computer the computer is sending a font which the receipt printer does not have built in. My question is, is there a way to find out what fonts are being sent to the printer? This would let me narrow down what I need to modify in the Windows font folder. Thank you!

• Recovering a broken NTFS filesystem?

  - by OverTheRainbow

  A much-needed Windows Update broke a Vista laptop that was running fine until then: After booting up, Windows displays "Please wait..." but it never goes anywhere. I waited for a couple of hours, there is a bit of disk activity, but it didn't work out in the end. I booted with the Vista DVD, chose "Repair your computer" which said that there was nothing wrong :-/ Next, I booted it up with a Linux USB keydrive, and ran Gparted 0.8.1 (which includes ntfsresize v2011.4.12AR.4 libntfs-3g) which displays a bunch of warnings for the NTFS partition where the Vista system is located such as: ntfs_mst_post_read_fixup: magic: 0x00000000 size: 1024 usa_ofs: 0 usa_count: 65535: Invalid argument Record 16 has no FILE magic (0x0) Next, I ran ntfsfix /dev/sda2, which said: Mounting volume... OK Processing of $MFT and $MFTMirr completed successfully. NTFS volume version is 3.1. NTFS partition /dev/sda2 was processed successfully. Next, I rebooted Vista, which did a CHKDSK, before rebooting. But I'm still getting nowhere with "Please wait..." Before I copy the user's data to another host and reinstall Vista from a DVD, does someone know what I could try? Thank you. Edit: In case someone else has the same issue... After the BIOS, hit F8 and choose "Repair your computer", followed by "Toshiba HDD Recovery". In addition to a 1,5GB partition labelled "WinRE", the hard disk contains a second partition labeled "Data" from which the application will fetch a system image and reinstall it in the "Vista" partition. Make sure you copy your data out of the system partition before doing this.

• Graphics card ATI Asus 9250 128 MB AGP problem.Monitor switching off.

  - by Dominick1978

  I have an old system with these specs: Motherboard: Via P4x266a (with AGP 4x) CPU: P4 1,7 Ghz Memory: 1152 MB DDR SDRAM Graphics card: Voodoo 3 2000 16 MB PSU: 300 Watt It also has 1 dvd-rom, 1 dvd-rw, 2 hard drives (all 4 connected via molex) , 1 sounblaster sound card and 1 ethernet card (both connected via pci). OS: XP Pro Recently I bought Asus 9250 128 MB AGP to replace voodoo.Wnen I switch on the pc the initial screens (until after the xp logo) sometimes are distorted with blurred colours.When XP are loaded there is some flickering but the rest are ok.XP can't recognize the card seeing it as just a VGA adapter.I have downloaded the latest xp drivers from ATI website and installed them.Then after the restart everything is ok (no distorted image or blurring) until after the xp logo.After this the monitor turns off while the pc is still running.I have tried many drivers but the problem persists (of course I removed the voodoo drivers before from the display adapter properties).Only once I have managed to enter XP (after changing BIOS features for graphics card from 256 MB to 128 MB) but the drivers on the control panel had an exclamation mark (ati 9250!) and below them ati 9250 secondary without ! under the display adapter tab and the ATI catalyst program said that it couldn;t find the card.That was the opnly time I went beyond the xp logo.Now the monitor auto switcheS off. So, what do you think? 1)Is this a broken card? 2)Is it the drivers of the card? 3)Is it PSU fault? 4)Anything else? Thanks for your help and excuse my english!

• Mac Outlook showing all links in smart quotes?

  - by user2727128

  I was given the task of fixing my friend's email today and really don't know what the problem is. When an email is sent from his laptop (Mac) from Outlook the email address link in the signature shows exactly like this: [email protected]<mailto:[email protected]>. Additionally the website link displays like this: www.website.com<http://www.website.com>. And lastly, the image comes through as cid:randomstringofnumbers. When I sent him an email and he sent one back it converted my signature to same weird formatting. Plus, even in the header where it shows our emails, they are displaying the same way: [email protected]<mailto:[email protected]>. And the weirdest thing is that this problem seems to be "compounding". So when I scroll down to the last, most recent email in the thread I see this www.website.com<http://www.website.com> next email shows this: www.website.com<http://www.website.com><http://www.website.com> and the next this: www.website.com<http://www.website.com><http://www.website.com><http://www.website.com> This is happening to the emails too, everywhere. I'm thinking this might be something to do with smart quotes and the auto formatting but I'm not sure. Could this be the problem? And if so how do I fix it?

• solution for an offline server

  - by dashmug

  I'm trying to setup a development server at work that will ideally be able to test drive a couple of projects in PHP, Rails, or Django (not always running at the same time). I develop the apps locally on a Mac and then I'll put the projects up on this server for testing with my actual users (non-techies) before deploying to a production server. My problem is that we have a very poor internet connection (almost negligible) at work and doing the usual apt-get/yum/ports (make, clean, install) processes for setting up servers always get their packages from online repositories somewhere. I know I could probably download the source and then compile them myself but that's going to be too much of a hassle for me. I'm thinking about two solutions: Plan A: Run a server VM on my Mac and then use this VM as the source repository for the offline server. I've read about Ubuntu's apt-proxy and it seems to be good enough though I haven't tried it yet. I'm not sure if this is possible but can I simply do apt-get install nginx --downloadonly so that the package and its dependencies will be downloaded into my VM and my server can use the VM as the source repo for apt-get? Plan B: Run a server VM on my Mac (which I can setup/update easily when I'm home) and then clone the VM to the offline development server. Maybe I should simply make the server a VM host so I can simply copy the VM over. I think this is okay for the first-time setup but subsequent updates will take too long (cloning the VM image). If I was working on Windows, I imagine it'd be easier because most services have an installer file that I can download and then run at the server. If you could suggest another way, it would be much appreciated. Update: From Michael Hampton's answer, I found a possible solution which is apt-cacher. I also found this page on Ubuntu's website. I wonder if there is a better tool than this one.

• Powerpoint not drawing in slide properly...

  - by commradepolski

  So got another issue to post about. I have a user here who uses powerpoint a lot, Office 07 with SP2. When he opens up the presentation, powerpoint opens fine without errors, but does not draw in the main slide properly. So to better explain that, the list on the left hand side, that shows the slides and what order they are in, loads up fine. You can see the slides and the content etc. When you click on a slide, to edit it, it does not draw in on the editing screen. Not really sure how to explain that. The screen where the work on the slide is done, is what is affected. This is a screen shot from my pc not the users. So instead of the screen saying "Click to add title" it would be improperly drawn such that if I were to drag an explorer window across it, it would leave a trail. I have tried reinstalling office, updating it, as well as giving the user a new windows image and nothing has helped. Any help or advice is appreciated.

• Apache not routing to tomcat on correct Virtual host

  - by ttheobald

  We are looking at moving from Websphere to Tomcat. I'm trying to send traffic to tomcat from apache web server based on the virtual host directives in apache web server. After some playing around I have it sort of working, but I'm noticing that if I have a JKMount directive in the first VirtualHost in apache, all virtualHosts will send to the application server. If I have the JKMount in Virtual hosts further down in the configs, then only that VirtualHost works with the request. For Example, with the configs below here are my symptoms mysite.com/Webapp1/ -- I resolve to the proper application mysite2.com/Webapp1/ -- I resolve to the proper application (bad!) mysite.com/MonitorApp/ -- I resolve to the proper application mysite2.com/MonitorApp/ -- I resolve to the proper application (bad!) mysite.com/Webapp2/ -- I DO NOT get to the app (good) mysite2.com/Webapp2/ -- I resolve to the proper application Here's what my web server virtualhosts look like. <VirtualHost 255.255.255.1:80> ServerName mysite.com ServerAlias aliasmysite.ca ##all our rewrite rules JkMount /Webapp1/* LoadBalanceWorker JKmount /MonitorApp/* LoadBalanceWorker </VirtualHost> <VirtualHost 255.255.255.2:80> ServerName mysite2.com ServerAlias aliasmysite2.ca ##all our rewrite rules JkMount /Webapp2/* LoadBalanceWorker </VirtualHost> we are running apache webserver 2.2.10 and tomcat 7.0.29 on Solaris10 I've posted an image of our architecture here. http://imgur.com/IFaA6Rh I HAVE not defined VirtualHosts on Tomcat. Based on what I've read, my understanding is that it's only needed if I'm accessing Tomcat directly. Any assistance is appreciated. Edit Here's my worker.properties. worker.list= LoadBalanceWorker,App1,App2 worker.intApp1.port=8009 worker.intApp1.host=10.15.8.8 worker.intApp1.type=ajp13 worker.intApp1.lbfactor=1 worker.intApp1.socket_timeout=30 worker.intApp1.socket_connect_timeout=5000 worker.intApp1.fail_on_status=302,500,503 worker.intApp1.recover_time=30 worker.intApp2.port=8009 worker.intApp2.host=10.15.8.9 worker.intApp2.type=ajp13 worker.intApp2.lbfactor=1 worker.intApp2.socket_timeout=30 worker.intApp2.socket_connect_timeout=5000 worker.intApp2.fail_on_status=302,500,503 worker.intApp2.recover_time=30 worker.LoadBalanceWorker.type=lb worker.LoadBalanceWorker.balanced_workers=intApp1,intApp2 worker.LoadBalanceWorker.sticky_session=1

• how to build network across buildings ?

  - by Omie

  Hi ! I need some help in building a network between hundreds of computers spread across multiple buildings of my college. Yes, I'll be doing this as a part of my college project. Please see this image, it will give you enough idea of what I'm trying to achieve. http://i.imgur.com/rOohx.png All the computers in all buildings should be able to connect server. Once network is up, there will be a set of services over intranet and network use will be moderate. well, say there will be an email server and a http server. My point is, I cannot afford much of performance loss. It feels easy to connect computers inside 1 building to each other, however, I'm clueless as to how to connect all of them to server. I mean, just 1 cable won't be enough to connect 1 building to server, right ? How should I go with it ? I am not expecting detailed configuration. Just heads up will do :) Thanks
